Theano: A Python framework for fast computation of mathematical expressions
The Theano Development Team, Rami Al-Rfou, Guillaume Alain +110
Theano is a Python library that allows to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently. Since its introduction, it has bee…
Picture changing operators in supergeometry and superstring theory
Alexander Belopolsky
Geometrical meaning of superstring pictures is discussed in details. An off-shell generalization of the picture changing operation and its inverse are constructed. It is demonstrat…
New Geometrical Approach to Superstrings
Alexander Belopolsky
We present a new geometrical approach to superstrings based on the geometrical theory of integration on supermanifolds. This approach provides an effective way to calculate multi-l…
De Rham Cohomology of the Supermanifolds and Superstring BRST Cohomology
Alexander Belopolsky
We show that the BRST operator of Neveu-Schwarz-Ramond superstring is closely related to de Rham differential on the moduli space of decorated super-Riemann surfaces P. We develop…
String center of mass operator and its effect on BRST cohomology
Alexander Astashkevich, Alexander Belopolsky
We consider the theory of bosonic closed strings on the flat background R(25,1). We show how the BRST complex can be extended to a complex where the string center of mass operator,…
Who changes the string coupling ?
Alexander Belopolsky, Barton Zwiebach
In general bosonic closed string backgrounds the ghost-dilaton is not the only state in the semi-relative BRST cohomology that can change the dimensionless string coupling. This fa…
